1. 填一填。（建议4分钟完成）
$15:(\ \ \ \ \ ) = 9:2$ $\frac{90}{30}=\frac{(\ \ \ \ \ )}{3}$ $\frac{3}{4}=\frac{(\ \ \ \ \ )}{12}$
$8:0.2 = (\ \ \ \ \ ):0.3$ $\frac{42}{(\ \ \ \ \ )}=\frac{10}{5}$ $\frac{5}{(\ \ \ \ \ )}=\frac{15}{60}$
$\frac{1}{5}:\frac{1}{25}=30:(\ \ \ \ \ )$ $\frac{75}{12}=\frac{(\ \ \ \ \ )}{4}$ $\frac{(\ \ \ \ \ )}{7}=\frac{27}{63}$
$(\ \ \ \ \ ):\frac{1}{4}=12:0.75$ $\frac{(\ \ \ \ \ )}{7}=\frac{21}{49}$ $\frac{9}{5}=\frac{36}{(\ \ \ \ \ )}$
$8\times(\ \ \ \ \ ) = 4\times35$ $\frac{(\ \ \ \ \ )}{3000}=\frac{1}{15000}$ $\frac{3.2}{(\ \ \ \ \ )}=\frac{8}{5}$
$(\ \ \ \ \ )\times\frac{1}{6}=1.5\times6$ $\frac{3}{(\ \ \ \ \ )}=\frac{42}{56}$ $\frac{8}{9}=\frac{3.2}{(\ \ \ \ \ )}$
$1\frac{1}{2}\times(\ \ \ \ \ ) = 0.75\times\frac{1}{2}$ $\frac{24}{64}=\frac{(\ \ \ \ \ )}{16}$ $\frac{6}{(\ \ \ \ \ )}=\frac{5.5}{7.7}$
$\frac{3}{7}\times(\ \ \ \ \ )=\frac{9}{2}\times\frac{7}{3}$ $\frac{60}{75}=\frac{4}{(\ \ \ \ \ )}$ $\frac{(\ \ \ \ \ )}{3}=\frac{4}{1.5}$

2. 计算下面各题，能简算的要简算。（建议5分钟完成）
$17.2 - 5.2\div0.8\times0.6$ $10.7 - 0.2\times1.9 - 8.62$
$17\times15\times(\frac{8}{15}-\frac{3}{34})$ $24\div1.5 + 2.5\times0.6$ $3232\div1515$
$\frac{17}{18}\div[\frac{3}{4}\div(\frac{7}{16}-\frac{1}{4})]$ $17\div64\times1.25+\frac{15}{64}\div\frac{4}{5}$

答案： $\frac{49}{2}$@@5@@8@@17.5@@$\frac{32}{15}$@@$\frac{17}{72}$@@$\frac{5}{8}$
